'5G, even 6G': What is Trump talking about in angry tweet about foreign companies – and is the technology he wants even possible in America?

Next-generation 5G technology is only just making its way to market after a decade of development, but Donald Trump is already demanding the rollout of 6G in the United States. The US President did not elaborate on what 6G might involve, with even his understanding of 5G appearing basic in a series of tweets on Thursday. He described it as "far more powerful, faster and smarter" than current 4G technology, while also revealing his concerns that the US is lagging behind in the deployment of 5G. "I want 5G, and even 6G, technology in the United States as soon as possible... American companies must step up their efforts, or get left behind," Trump tweeted. His comments come just days after the founder of Chinese technology giant Huawei – who are widely regarded as one of the pioneers of 5G – said the US risks falling behind the rest of the world when it comes to 5G rollout.
